Hair testing is increasingly recognized as a robust method for identifying drug and alcohol use. It offers a comprehensive history of substances through biomarkers embedded in the hair strands. Collected near the scalp, hair samples can indicate up to a three-month period of alcohol and drug exposure. Hair collection is straightforward, not easily manipulated, and convenient for shipping.
A 1.5-inch sample of approximately 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp yields the optimal 100mg for analysis. For EtG, additional parameters, or tests beyond 10 panels, a 150mg specimen is advisable. It's best to weigh the specimen with a jeweler's scale. In the absence of scalp hair, an equivalent amount of body hair is suitable. When mentioning head hair, it refers specifically to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample in a laboratory system, confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data not captured by an electronic chain of custody system.
Screening entails an initial assessment for substance misuse. Although Screening offers an economical means to exclude drug use in most cases, a confirmed result is required for legal admissibility. Any samples showing presumptive positives in Screening must undergo further confirmation.
Should a sample indicate a presumptive positive during Screening, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging procedure to execute.
The Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo a wash prior to confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
